Async Queue – One of my favorite programming interview questions

For the past 7+ years, I've been conducting a programming interview that has been a true personal favorite of mine. It was passed down to me from good friends (Jeremy Kaplan and Carl Sverre, and it was the latter whom I believe invented it). This interview has probably been given by us between 500-1000 times across different companies, and upon googling for "async queue interview", I see tons of results. So, it's probably fine for me to blog about it. My main goal with this blog post is to disc

‘Doctor Who’ Will Keep the Fifteenth Doctor Alive with New Comics

While BBC determines what to do with Doctor Who after its latest season, the comics are hoping to give you more Fifteenth Doctor adventures. The upcoming Prison Paradox miniseries comes courtesy of returning Who comics writer Dan Watters and artist Sami Kivelä (Abbott). Waters previously wrote the 2024 miniseries starring the Fifteenth Doctor, and in this new tale, he’s putting Fifteen and Belinda Chandra on an “unlikely team of allies” looking to infiltrate an alien prison holding “monsters an

Elon Musk Is Selling His Political Party Like a Tesla

Less than 24 hours after launching his political party, Elon Musk is already playing hype man for the movement he claims will disrupt America’s broken political system. The richest man in the world took to X (formerly Twitter), the platform he owns, early Saturday morning to promote and to articulate the need for The American Party, his newly announced third party aimed at breaking what he calls the “uniparty” stranglehold of Democrats and Republicans. The move has drawn sharp criticism from su

How Brex is keeping up with AI by embracing the ‘messiness’

Companies have struggled to adopt the right AI tools as the technology evolves at a far faster pace than their slow sales cycles. Corporate credit card company Brex is no different. The startup found itself facing the same issue as its enterprise counterparts. The upshot: Brex completely changed its approach to software procurement to ensure they wouldn’t get left behind. Brex CTO James Reggio told TechCrunch, at the HumanX AI conference in March, the company initially tried to assess these

Researchers seek to influence peer review with hidden AI prompts

In Brief Academics may be leaning on a novel strategy to influence peer review of their research papers — adding hidden prompts designed to coax AI tools to deliver positive feedback. Nikkei Asia reports that when examining English-language preprint papers available on the website arXiv, it found 17 papers that included some form of hidden AI prompt. The paper’s authors were affiliated with 14 academic institutions in eight countries, including Japan’s Waseda University and South Korea’s KAIST

New study offers clues about what makes someone cool

Is there a secret sauce that helps explain why people as different as David Bowie, Samuel L. Jackson and Charli XCX all seem so self-assured and, well, cool? A new study suggests that there are six specific traits that these people tend to have in common: Cool people are largely perceived to be extroverted, hedonistic, powerful, adventurous, open and autonomous. The study, which was published on Monday in the Journal of Experimental Psychology: General, surveyed nearly 6,000 participants from

Elon Musk Forms a New Political Party to Challenge Trump and the Republicans

As he had previously vowed, Tesla CEO Elon Musk officially announced the formation of a new, third political party on Saturday, July 5, 2025. This dramatic move comes just hours after President Donald Trump signed his “One Big Beautiful Bill” into law, a sweeping budget measure that implements massive spending cuts and eliminates nearly all federal climate and clean energy programs, legislation Musk staunchly opposed. The announcement was definitive. “Today, the America Party is formed to give

Tesla Robotaxi Rider Gets Bizarre Call Saying She Has to Exit Vehicle Immediately

YouTuber and Elon Musk stan Ellie Sheriff had a bizarre experience during her first Tesla robotaxi ride in Austin, Texas. As seen in a video she shared on her channel, "Ellie in Space," over the weekend, Sheriff got a strange call from the EV maker mid-ride, asking her and her fellow passenger to literally leave the vehicle due to incoming weather. "So we had to get out of the robotaxi, because weather is coming in," Sheriff said in the video while standing in the middle of a windy field. The

Apple is reportedly working on a cheaper MacBook, but will it matter?

This week, we heard some news from analyst Ming-Chi Kuo about Apple entering a new segment of the laptop market. The company is reportedly working on a new MacBook at a lower starting price point than the MacBook Air, and it’ll apparently pack the A18 Pro chip found in iPhone 16 Pro and iPhone 16 Pro Max. While a cheaper MacBook is certainly a welcome add, the question truly stands: will Apple do it properly, or will it serve as another decoy model? Rumor refresh To quickly recap, the cheaper

Here are three reasons why AirPods Pro 2 are still worth picking up in 2025

We’re likely going to see yet another version of AirPods Pro this September, alongside the launch of the iPhone 17 lineup. Despite the current set of AirPods Pro coming up on nearly three years old, I don’t think that those in the market to buy new AirPods should necessarily waste their time waiting for a potentially upcoming model. AirPods Pro 2 keep getting better Even though we should get a new pair of AirPods Pro in the coming months, that hasn’t stopped Apple from continually making this

Is It Cake? How Our Brain Deciphers Materials

One of the greatest questions of the modern age is: Is it cake? As in: Is it an espresso machine, or cake? Paint can, or cake? Air fryer, or …? Millions of viewers have watched rapt as TikTok bakers slice or bite into inedible-looking objects with fluffy, frosting-filled innards … or have tuned into Is It Cake?, the aptly named Netflix show. Why? As a form of entertainment, this kind of visual trick is hardly new. For centuries, artists have delighted in fooling us into thinking one material is

Elon Musk’s New Political Party Sparks MAGA Backlash Online

The suspense is finally over. Elon Musk, the visionary behind Tesla and SpaceX, officially declared the formation of a new political party on Saturday, July 5, 2025.

ApplePay vs. Alternative Payment Services

2025-07: "ApplePay vs. Alternative Payment Services" by Marc Stibane Thought experiment Imagine an airport which issues a frequent traveller card which millions of passengers have signed up for. This Airport demands from the shops in the airport mall to either only offer their traveller card for payments, or any other payment method, but not both. So if merchants offer alternative payment methods to customers, they may not offer the airport traveller card. This would be ridiculous, right? We

Is It Time to Stop Protecting the Grizzly Bear?

This story originally appeared on Vox and is part of the Climate Desk collaboration. In the early 1900s, long before smartphones and selfie sticks, tourists flocked to Yellowstone National Park—not for the geysers or scenery, but for a grotesque show: a nightly spectacle of grizzly bears raiding cafeteria scraps from open-pit landfills like desperate, starving pirates. The bears were in dangerous proximity to humans: Hungry bears tore at open car windows. Tourists posed a little too close with

Incapacitating Google Tag Manager (2022)

"We're long past the days when it was possible to simply say "no" to corporate stalking without consequence. Today, when we say "no", we get punished for it. But that only goes to show WHY, more than ever, we should be saying "no"." Google Tag Manager. It's a product which, by design, cloaks a range of the Internet's most invasive and unethical scripts in an opaque closet, then springs them out in disguise. Combining immense power with obfuscation and vast scale of use, Google Tag Manager is th

Who is Soham Parekh, the serial moonlighter Silicon Valley can't stop hiring?

In the last week, social media users have shared dozens of stories about encounters with Soham Parekh, a software engineer who seems to have been simultaneously working at multiple Silicon Valley startups — unbeknownst to the companies — for the last several years. But who is Parekh, how did he pull off his career as a serial moonlighter, and why can’t Silicon Valley get enough of him? Origins of virality The saga all started when Suhail Doshi — CEO of image generation startup Playground AI —

Ask HN: Worth leaving position over push to adopt vibe coding?

My company is increasingly pushing prompt engineering as the single way we "should" be coding. The CEO & CTO are both obsessed with it and promote things like "delete entire unit test file & have claude generate a new one" rather than manually address test failures. I'm a 'senior engineer' with ~5 years of industry experience and am considering moving on from this company because I don't want 1. Be pushed into a workflow that will cause my technical growth to stall or degrade 2. Be overseeing

Elon Musk Teases ‘Fireworks’ as Trump Signs His ‘Big, Beautiful Bill’

Elon Musk, the world’s richest man, spent the Fourth of July doing what he does best: stirring speculation, igniting controversy, and hinting at big political moves. All from behind a keyboard. The Tesla and SpaceX CEO kicked off America’s Independence Day with a patriotic post on his platform X (formerly Twitter): “🇺🇸🇺🇸 Happy birthday, America! 🇺🇸🇺🇸” 🇺🇸🇺🇸 Happy birthday, America! 🇺🇸🇺🇸 — Elon Musk (@elonmusk) July 4, 2025 But it was his follow-up that really set off alarms: “Great day for som
